Steve, but.... You originally have spoken about fossil fuels, not the specific chemicals called ODS (ozone depleting substances), which are different from the fuels which the Trump administration would like to extract.
Fossil fuels seem to have an impact, but secondary. the ozone layer issue deserves a dedicated thread probably. Too late for me to start searching. It may even be reconstituting itself now.
t's important to distinguish between the direct causes of ozone depletion and the broader impacts of fossil fuel combustion. Here's a breakdown:
Ozone-Depleting Substances (ODS):
The primary cause of ozone layer depletion is the release of man-made chemicals, specifically ozone-depleting substances (ODS). These include:
Chlorofluorocarbons (CFCs)
Hydrochlorofluorocarbons (HCFCs)
Halons
These substances release chlorine and bromine atoms in the stratosphere, which then catalyze the destruction of ozone molecules.
Fossil Fuels and Related Emissions:
While fossil fuels themselves don't directly release the primary ODS like CFCs, their combustion does contribute to atmospheric changes that have complex interactions with the ozone layer.
Burning fossil fuels releases various pollutants, including:
Nitrogen oxides (NOx)
These can have some influence on stratospheric ozone chemistry.
Greenhouse gases, such as carbon dioxide. These gases contribute to climate change, which in turn can affect stratospheric temperatures and circulation, indirectly influencing ozone levels.
Therefore, fossil fuel combustion has indirect effects on the ozone layer, primarily through its contribution to climate change.
Key takeaway:
The direct and most potent cause of ozone depletion is ODS, which were historically used in various industrial and consumer applications.
Fossil fuels main impact is on climate change, which then has a secondary impact on the ozone layer.
